When one part divides a span into three beats and another into two, the result is a 3:2 polyrhythm. These layers are fundamental to many West African and Afro-Cuban traditions and appear in jazz, progressive rock and electronic music.
Polyrhythms create a sense of motion and complexity even when each individual part is simple.
